Gibney started investing when his
Stanford University roommate
Ken Howery co-founded
PayPal, the electronic payments company, and offered Gibney the chance to buy "friends and family" shares. After investing in PayPal, Gibney worked as a litigator but was soon hired by
Peter Thiel after Thiel sold PayPal to
eBay in 2002. Gibney worked at Thiel's
hedge fund, Clarium, until 2008, making occasional private investments including in
Palantir Technologies in 2005 and later in
DeepMind, which was acquired by
Google for around $450 million in 2014. He then moved to
Founders Fund, a venture capital fund started by Thiel. Thiel and Founders Fund were the earliest outside investors in Facebook,
SpaceX, and Palantir, and made other investments including in
AirBnB,
Lyft,
Spotify, and Stemcentrx, which
AbbVie acquired for $10 billion a few years after Founders Fund's investment. Gibney wrote Founders Fund's controversial statement of ideology,
What Happened to the Future?, in 2011, which called for more aggressive investments in breakthrough technologies and became a widely cited article in the technology community. He also wrote other articles about start-ups and technology and lectured on these subjects, as well as Silicon Valley's "libertarian problem". Gibney left Founders Fund in December 2012. He continued to make personal investments, though he made few since 2015, stating in a January 2016 speech in
Zurich that he believes start-ups are richly valued and expressing concern that too many start-ups are remaining private for too long, creating misalignment of incentives between executives and employees and investors. ==
